It really depends on the specific plot and character development in the manhwa. Sometimes it happens early on, and in other cases, it might take a while.
It's a complex tale of a female character who finds herself in a challenging relationship with a tyrant. There are lots of twists and turns along the way.
I think 'though i am an inept villainess novel' is quite interesting. It often takes a fresh perspective on the villainess trope. Instead of the typical all - powerful and evil villainess, this type of novel focuses on one who is inept, which can lead to some really humorous and unexpected plot twists.
To be a successful villainess in a manhwa, you need to have a strong personality and a clear goal. Also, a unique style and the ability to outsmart others are important.
